Abstract

The present disclosure relates to a work machine, in particular in the form of a dump truck or of a truck, having a diesel electric traction drive, comprising at least one internal combustion engine, at least one alternator, at least one set of power electronics as well as at least one electric motor, wherein the power electronics are arranged at least partially in the region of a driven driving axle of the work machine.

Claims

1. A work machine, having a diesel electric traction drive, comprising at least one internal combustion engine, at least one alternator, at least one set of power electronics as well as at least one electric motor,

the power electronics are at least partially arranged in the region of a driven driving axle of the work machine.

2. The work machine of claim 1, wherein the work machine is in the form of a dump truck or of a truck.

3. The work machine in accordance with claim 1, wherein the at least one alternator, the power electronics and the at least one electric motor are arranged behind one another at the vehicle in a direction of travel, and at a vehicle frame.

4. The work machine in accordance with claim 1, wherein the power electronics are arranged at least partially between the alternator and the driven driving axle.

5. The work machine in accordance with claim 1, wherein the power electronics are arranged at least partially between two frame beams of a vehicle frame.

6. The work machine in accordance with claim 1, wherein the power electronics are structurally mounted at least partially at an outside at the vehicle frame.

7. The work machine in accordance with claim 1, wherein the power electronics are divided into two or more functional modules and each functional module has an encapsulated housing.

8. The work machine in accordance with claim 7, wherein the functional modules are arranged in the frame between the frame beams and/or at the outside at the vehicle frame.

9. The work machine in accordance with claim 1, wherein the power electronics are accessible for servicing, installation and/or dismantling with an upwardly tilted skip of the work machine.

10. The work machine in accordance with claim 9, wherein a lifting gear for the installation or dismantling is provided at the work machine, at least in the region of the skip.

11. A system, comprising:

a work machine having a diesel electric traction drive including at least one internal combustion engine, at least one alternator, at least one set of power electronics as well as at least one electric motor, wherein the motor is coupled to a driving axle driving a wheel of the work machine, and wherein the power electronics are arranged adjacent the driving axle of the work machine between parallel frame rails of the work machine.

12. The system of claim 11, wherein the engine is longitudinally mounted in the work machine forward of the driving axle, the work machine further having an upper walking deck positioned vertically above the frame rails, the rails each formed as longitudinal beams coupled together to one another.

13. The system of claim 12, wherein the power electronics are housed by at least one housing the housing fully between the two rails, where the housing does not extend vertically above a top of the rails along an entire longitudinal length of the housing.

14. The system of claim 13, wherein the work machine further includes an operator cab.

15. The system of claim 14, wherein the work machine further includes a skip.

16. The system of claim 15, wherein the work machine further includes a radiator module.

17. The system of claim 16, wherein the radiator module is positioned at a front of the work machine without any other components forward of the radiator module, the radiator module coupled below the upper deck.

18. The system of claim 17, wherein at least two power electronics housings are provided adjacent one another, and where outside side walls of the housings are each adjacent and in face-sharing contact with inner side walls of the respective side rails.
